CoNARD, a citizen "of the United States, residing at N orristown, in the county of Montgomery and the State of Pennsylvania, have invented a new and useful Improvement for, Reinforce ment for Concrete.

My invention relates to reinforcing con crete structures and'the like. It consists in the employment of the shapes in such manner that suchmetal parts may be made in'an ordinary-structural steel or iron shop requiring the use of no special 'machinery or parts.

1 The nature and scope of my invention will be morereadily understood from the following description taken in connection with the accompanying drawings forming part hereof, in which Figure 1 is a side elevational view pprtly in section of a portionof a structure em odying the main features lineof the concrete being shown in dotted Fig.2 is a seetionalhplan view, taken igr 3 is a vertical on the line 22 of Fig. 1.

of Fig. 1. Fig.

section taken on the line 33 4 is a similar View taken on the line 44 of Fig. 1. Figs. 5, 6, .7, 8 and 9 are sections showing various shapes that may be used as tension members in the main or cross beams and the manner of bers thereto, and Fig. 10 is a similar view showing the use of an angle as a shear mem her in place of the flats shown in the other figures.

. Referri to the drawings 15 is the column of any pre erred form of rolled or built up section. Joined to column' 15 in any desired manner is the tension member 16whic'h' may consist of any of the usual rolled structural'shapes such as channels, angles, tees,'I beams, zees, .or the like.

the finished concrete girder to .thereby take care of-.the.,-.tensilestresses existing 1n the samex The preferred manner of connecting consists in seating its end adjacent to'the column on a connection angle 17 of the usual type orotherwise as of a column,

may' be found convenient andfriveting or bolting thereto. Additional: connection angles 18 riveted or bolted to the sides of member 16 and to column 15 maybe used 1f-desired. Riveted or bolted to member 16, at

which may carry projections 20 at their up per ends consisting of angles as shown or otherwise or members 19 may simply be bent Patented'June 25,1907. y

toward column 15 are the shear members li over if desired. The purpose of projections 20 is to tie members 19 into the concrete at their upper ends. The shear member 19 adjacent to the column '15 is riveted or bolted to the said column either by means of a connectiofu angle eted directly to some other projecting fiat surface of the column as is desired so as to give as'trong and rigid connection between the girder and column capable of resisting stresses in the girder and the Wind and other lateral forces structure. Rods or bolts 21 may be laced in holes in member 16 to secure the etter adherence of the concrete.

Supported by member 16 are the tension mem ers 23 of the transverse or cross beams,

so positioned and roportioned as to he be ow the neutral axis of said beam to withstand the tensilestresses existing'inthe same when com leted. bers 23 also have riveted or shear members 24 suitably located and inf clined and if desired carrying projections 25, at their upper ends.
